T o all 'whom z't may concern: Be it known that I, WILLIAM Wnnn'r,

I a citizen-of the nited States, residing at Brooklyn, inthe county ofKings' and State the provision lof Va. mecharnically operable of NewYork, have invented newand useful Improvements in Massage Devices, ofwhich the following is a specification.V

ThisY invention .relates to improvements 1n massa-ge apparatus. Y

The principal object of the invention is massage devicewherein thevibrations are Aimparted to the surface to be massaged at Y right anglesto said surface whereby/'the action of the apparatus will not tend to'loosen the hair' or stretch vthe skin when V using the apparatus for ascalp massage. ,I

29 /or regulating Another object of the invention is to provide lanapparatus whichincludes a means thepforce of the-vihratory members.

A further ohject ofthe invention resides. in the construction of'amassage apparat-us which is simple in construction and operation, andinexpensive to manufacture.

With these vand other objects in view," vthe invention resides incertain novel construction and combination and arrangement of parts, theessential features of which 'are' hereinafter fully described, areparticularly pointed out 4in the appended claims, and are f illustratedin the accompanying drawing,

ing, the reference numeral 10 designates a tubular. member which servesas a handle for my device, and which carries a .cylindrical casing 11 atone end thereo. A remove able cover 12 closes the bottom of the casingto permit access to the interior should it be desired to replace'any 'ofthe working parts.

Mounted within the wall and cover, is a partition 13, and for I rotationin the top wall, partition and cover is a reduced end 14 of a shaft 15.The shaft 15 may receive its power from any suitable casing between thetop mechanism might be provided.

Mounted within the casing 11 isan outer set of vibratory members 16 andan inner set of vibratory members 17 which are artion -and eachcomprises a cylinder 18 having its vopposite ends mounted in the coverand partition, for slidably accommodating a plunger 19, the shank otwhich extends beyond the cover as clcarlyshown in Figure source such asa motor through the use of a flexible shaft, or any suitable actuating Y`ranged in circular formation concentric to .the axisof the shaft 15..Both sets Aof vi- 'Y bratory members are identical in construc- 1 ofthe drawing. Interposed between the head l20 of each of the plungers andthe cover 12 is a spring21, and resting upon the head is a sphericalmember 22 of a circumference to move freely into its respective cylinder18. The spring normally holds the 'spherical member against theunderside of the cam disk` 23 which is provided with oppositely disposedhigh and low surfaces 24 and 25 respectively. The disk is connected tothe reduced end 14.01 the shaft 15 for rot-ation therewith. From thedescription thus far,

4it will be seen that as the shaft rotates, the

low surface of the disk engages the spherical members? to depress therespective plungers against the tension of the springs to extend thesame further from the casing, and as the spherical members engage thehigh surface ofthe cam disk, the springs21 will return the plungers toretracted position. Brieiiy, all of the plungers are movingsimilitaneously, either in an outward or an inward direction. lfdesired, the shanks'of the plungers might he provided with rubber tips-for direct contact with-the surface to be massaged, but for adjustingthe pressure of the plungers,-I desire vto enclose the same in a mannernow to be described.

Encircling the casing 11 at the lowerY end thereof, is a collar 25aformed with diametrically spaced vertical Vslots 26 through which passstuds'27 carried bythe side wallsvof the casing. The studs are" threadedto re-A ceive thumhnuts28 whereby the collar may he held in variouspositions of vertical -adjustment. The lower end ofl the collar isformed with an annular flange 29 which extends on opposite sides of theperiphery of the collar, and seated the inner portion of theflange-andthe cover-.12 is a spring A30l which tends to exert an outwardYpressure against the col1ar. L The outside portion of the flange 29 isslotted as at 31.

at oppositely disposed points for removably attaching thereto a cushionmember 32. The member 32 comprises a flexible disk of material 33 ofrubber or the like, which has its edges secured to a ring 34. The ring34 is formed with oppositely disposed flanges 35 :for registration withthe slots 3l of the flange 29 when attaching the member to the collar.After the flanges 35 are passed through the slots 31, the member isgiven a slight turn to lock the flanges 35 over the outside portion ofthe flange 29. From the above description, it will be seen that thepiece of material 33 may be adjusted with relation to the ends of theplungers so that the force of vibration may be varied accord- 'ing tothe amount desired.

In Figure 5 there is shown a modified formy of plunger in whichthespring is dispensed with. The cam disk 2 3- is provided with adepending track .24'-fwln'chv runs parallel to the horizontal face ofthe disk. The' plunger 19 has its bearings in the cover plate andpartition, and carries a pair of rollers 25 for co-action with thetrack. As the disk 23 rotates, the same will tend to extend the plungersor retract them by reaon of the corrugations on the disk.

It will be manifest that I have provided a massage apparatuswhere thevibration is imparted to the surface of the skin at right angle thereto,and the' action of the same is continuous as the vibrating plungers ares1multaneously operated.

` While I have described what I deem to be l. A massageapparatuscomprising a casing, a driven shaft having one end extendinginto said casing, a series of plungers mounted for reciprocatingmovement within said casing, the free ends of said plungers extendingrbeyond the casing, a' flexible strip positioned over the free ends ofsaid plungers, a Cam disk carried by said shaft and operable forcompressing said plungers against said ilexible strip, a collar adjustably mounted on said casing, and removable means for attaching saidiexible strip tovsaid collar.

2. A massage apparatus comprising a casing, a driven shaft having oneend extending into said casing, a series of plun gers mounted forreciprocating movement within said casing, the free ends of saidplu-ngers extending beyond the casing, a fiexible strip positionedoverthe free ends of said plungers, a cam disk carried by said'shaft andoperable for compressing said plungers against said fleXible strlp, acollar ad]ustably mounted on said casing, removable means for attachingsaid lexible strip to said collar, and a spring interposed between oneend of said casing and said collar.

, In testimony whereof I have aihxed my signature.
